Cradleboard Elementary

Monolithic Domes among the Ponderosa Pines

“It’s a perfect location,” said John Clark, Superintendent of Schools. “The buildings fitting so well into our setting helped us decide to go with domes.”

Cradleboard Elementary in Whiteriver, Arizona is on an Apache Reservation, at 7000 feet in Arizona’s high country. In 1998, the community completed three Monolithic Domes with an interconnecting central corridor. Nestled among the Ponderosa Pines, this 34,000-square-foot facility has a multipurpose dome with a cafeteria, gymnasium, and an arts/music area. It’s flanked by two domes with classrooms for 300 students and 13 teachers in kindergarten through grade five.

A real learning experience

Chances are that just about every one of Cradleboard’s students will not only remember the construction of its new Monolithic Dome school, but will also recall a dome-related assignment or two that had to be done.

Principal Barbara Nolan thinks so. “A dome automatically creates an interesting learning space for children,” Nolan said. “Right from the beginning our teachers incorporated much of what was going on in the construction and then the move as lessons for the kids.”

Getting inflated

According to Nolan, students watched all phases of the construction, but found the inflation of the Airforms the most exciting, by far. “Many could not believe it was going to be a school,” she said. “This resulted in an assignment asking them to write what they thought the structures could or should be. Spaceship probably was the most common response. The most unusual answer was a giant corral for rodeo classes and events.”

Another student project had fifth graders snapping photos, recording the progress of construction both outside and inside the domes. These will eventually be assembled into a historical scrapbook for visitors as well as future students.

Adapting to the round

Just before moving from the old buildings to the new, several classes were asked to make lists of what they thought should be taken from the old to be used in the new. “Many said windows,” Nolan reported. “They could not imagine being in windowless rooms. But a week later, there was no more talk about windows. They love the skylights each of the domes has and had no problem adapting.”

Teachers took longer to adapt. “At first, they found the pie-shaped classrooms a puzzle,” Nolan said. “What do we do with it? And how do we use it? Then the puzzle became a challenge, and they began coming up with some ingenious ideas. One teacher made her curved wall into a planetarium for the study of the solar system.”

Comparing costs

The primary factor influencing the School Board’s decision for domes, rather than modular or conventional structures, was financial.

“We did cost comparisons,” Superintendent Clark said, “and we visited Payson several times.” Asked what impressed him about Payson, Clark replied, “The calm and the quiet. The feeling of safety and security. We watched the kids and obviously they liked it.”

Cost of constructing the dome structures averaged $29.00 a square foot. Once completed, this average rose to $79.00 a square foot. “In today’s market, that’s a very good price,” Clark said.

Significant savings

“Our School District probably saved somewhere between $250,000 and $500,000 because our Business Manager, Frank Powell, acted as our Construction Manager and administered every phase of the project.”

At this point (1998), Cradleboard is too new for a realistic picture of utility costs. But Clark anticipates that they will be low. “We have a summer school program in session right now,” he said. “We’re using the air conditioning, but it’s mostly just to help the ceiling fans circulate the air.”

Principal Barbara Nolan agreed. She said that both adults and children find the domes’ interiors comfortable.

Solvable problems

As for problems, Nolan felt there were two. The first has to do with acoustics in the multipurpose dome. Unlike the other two domes, its ceiling does not have acoustical tiles and the cafeteria and gym floors are not carpeted. Plans to spray the ceiling with a special foam, this summer, should solve that problem.

The second problem has to do with storage. Nolan said, “The storage of heavy equipment, such as snowplows — which have fuel so they can’t be brought into a school building because of fire codes — somehow got overlooked. But we’re getting storage sheds.”

Welcome acceptance

When they were nomadic hunters, Apaches traditionally built wickiups — easily assembled wood and grass structures, shaped like a tepee, with a smoke hole at the top. Later, most lived in structures with corners, so at first many were dubious about domes. But making designs and plans available to the community, providing it with information, and welcoming spectators at the construction site soon eliminated doubts.

Nolan said, “The domes are beautiful. We get nothing but compliments on the architecture, design and colors."

Native American Motif — It adorns the dome walls in every area. Note the curved bench; it’s part of the dome.

Cafeteria — The cafeteria is part of the multipurpose dome that also includes the gymnasium and an arts/music area.

Round Theatre and Commons — Sporting an 8’ diameter skylight, it’s the center core of one of the Monolithic Domes that’s surrounded by classrooms. Windows in each classroom allow natural light in from the skylight.

Media Center — The Media Center is the core of the second Monolithic Dome. It also has an 8’ skylight and is surrounded by classrooms.

Unique Location — Cradleboard Elementary is on an Apache Reservation, at 7000 feet in Arizona’s high country, nestled among the Ponderosa Pines.

The Monolithic Dome school in Geronimo, Oklahoma was recently toured by Oklahoma’s Own newson6.com news reporter, Kelly Ogle. In his report, Ogle interviews NOAA Research Meteorologist Dr. Harold Brooks where he agrees that Monolithic Domes are safer and cheaper options for schools.

What’s a fertilizer blend plant’s number-one enemy? Moisture! If water gets into or condensation forms inside a storage unit, it quite quickly begins degrading the fertilizer and forming rust. But Monolithic uses a technology that keeps that troublesome process to a minimum.

Being the coinventor of the dome and the founder of the Monolithic Dome Institute has given David B. South the opportunity to not only fine tune the building process, but to create a company whose main mission is to make available Monolithic Dome technology to all the world. It is the hope of Monolithic to educate the public about Monolithic Domes and to provide professional services to its customers by creating a successful partnership with them through all phases of their dome design, planning and construction.

Storing fertilizer has long given the dry bulk storage industry headaches. Among its problems is corrosion, ruining equipment and costing money. The Monolithic Dome is a structure solving this problem for the industry.
